Journal of Multimedia Processing and Technologies Wang Yan1, 2 Le Jiajin3, Zhang Yun2 6 4 2015 In heterogeneous data integration, an effective machine learning model plays an important role in schema mapping. Schema mapping machine learning model and its probability learning improvement are analyzed in this paper firstly, and then the concept of multi -analyzer model with the method of fuzzy comprehensive evaluation is put forward to improve machine learning results’ efficiency and accuracy. Comprehensive experiments on multi-analyzer model confirm the effectiveness of multi -analyzer model.
